What to do with Lincecum

So I drafted this guy #34 overall(10 team h2h scoring league) thinking it was a steal as his average draft position is around 28. Started him every start early season but towards the middle I've only tried to start him on matchups I think are good and of course you guys all know how he has been doing. I have been having faith thinking he will pick it up but there seems to be no end in sight to his bad pitching. Anyways theres plenty of pitchers out there that I can pick up in place of him. Should I drop this guy or give him a couple more starts to see how he starts the second half?
